Background and Objective: Neuropathic pain is a large and difficult group of peripheral nerve diseases, which are complicated to treat. This study was designed to determine the effectiveness of acceptance and commitment therapy (ACT) on psychological well-being and pain perception among patients with chronic neuropathic pain.
Methods: This clinical trial was performed on 30 patients with chronic neuropathic pain who were referred to the Rohani Hospital and private clinic of a neurologist in Babol (Iran) in 2022. The patients were randomly divided into an interventional and a control group. The patients completed the psychological well-being scale (Ryff) and pain belief and perception inventory (Williams and Thorn) in the pretest. Then, ACT (120 minutes) was performed for the interventional group, 8 sessions a week. The patients completed the scales after the treatment course and 2 months after the posttest.
Results: In the first follow-up, there were significant differences between the two groups in terms of total score of psychological well-being (P<0.05), the subscales of self-acceptance (P<0.05), positive relationships with others (P<0.05), autonomy (P<0.05), environmental mastery (P<0.05), purpose in life (P<0.05), personal growth (P<0.05), the total score of pain perception (P<0.05), the subscales of belief in the stability of pain in the present (P<0.05) and belief in the mysteriousness of pain (P<0.05). The treatment results were maintained in the second follow-up phase. In the first follow-up, the subscales of belief in the continuation of pain in the future and belief in self-blame did not differ significantly between the two groups, but in the second follow-up, the subscales of belief in the continuation of pain in the future (P<0.05) and belief in self–blame (P<0.05) differed significantly between the two groups. In addition, the average psychological well-being in the intervention group was higher than that in the control group, and the average pain perception in the intervention group was lower than that in the control group.
Conclusion: This study shows the ACT could be an effective intervention for improving psychological well-being and pain perception among patients with chronic neuropathic pain.
